Hi Skip, I hope you don't mind me emailing you here, but I am reviewing the SR and looking at the doc you provided and will be working with the team to get to root cause. I have not reviewed all of the doc yet, but I suspect this could have something to do with sysplex aware zFS's and the enqueue's involved. I am not a zFS developer, but what I can tell you so far is that DSS thinks it got an enqueue on sysdsn (the cluster level enqueue). This tells me that DSS likely failed on the sysvsam enqueue that is obtained on the component name (omvs.root.data). I have yet to confirm this but will do that.
Since this is a staging system I wonder if there is an 'active', or mounted, zFS with the same component name within the sysplex? If so, this is what could be causing DSS to fail the enqueue. Once dss see's it cannot get the enqueue then we will try the quiesce. Would you be able to tell me if there is a mounted zFS in the sysplex with a component name of omvs.root.data? This is not much at the moment, but maybe it is something to get us heading down the right path.
